The lightpath reconfiguration performance of the stackable ROADM module with an optical amplifier has been evaluated experimentally for use in IP-over-CWDM ring networks. The lightpaths could be reconfigured and amplified successfully to connect longer distance than the allowable value without amplification. The packets could be switched to a new direct lightpath in the network such that the congestion...
A stackable module with a bidirectional CWDM amplifier has been proposed to introduce the optical amplifier into an S-ROADM for use in an IP-over-CWDM ring network, and the performance was evaluated experimentally. Packet transfer changes were monitored during the lightpath reconfigurations, including 2 lightpaths which needed optical amplifications. The result clarified that the lightpaths were reconfigured...
A monitored power pre-checking scheme has been proposed and implemented for the effective amplification management during lightpath reconfigurations in IP-over-CWDM networks with ROADMs. The pre-checking performance was examined in an experimental IP-over-CWDM network by reconfiguring lightpaths. As a result, the pre-checking function worked properly, and the lightpaths were reconfigured successfully...

A monitored power pre-checking scheme has been proposed and implemented for an effective optical amplification management in IP-over-CWDM networks with ROADMs. In the scheme, lightpaths are selected first to be checked whether the lightwaves should be amplified or not, before the lightpath reconfiguration, and the optical powers to be received by the optical transceivers for the lightpaths without...
